# Standalone Greeter Demo

This demo proves the SDK can run without HiveCast, without a managed platform,
and without committed credentials.

Run from the repository root:

```bash
pnpm install --frozen-lockfile
pnpm setup:nats
pnpm run doctor:standalone
pnpm demo:standalone
```

What it proves:

- the SDK packages build from this repo,
- this package builds against `@open-matrix/core`,
- a local unauthenticated `nats-server` is started for the demo only,
- `matrix package run` starts the actor from the package manifest against that
  broker,
- `--check-op echo` calls the actor over the Matrix runtime/NATS transport path,
- no managed host service, machine link, provider account, provider API key, or
  local HTTP control server is involved.
